WHIFFLETREE.

SPECIFICATION forming part of Lettersllatent No. 630,326, dated August8, 1899. Application filed February 8,1899. Serial No- 704,912. (Nomodel.)

To all whom, it may concern.-

Be it known that I, FRANK W. CHICKERING,

a citizen of the United States,residin g at Hardwick, in the county ofCaledonia and State of Vermont, have invented certain new and usefulImprovements in Whiffletrees; and I do declare the following to be afull, clear, and exact description of the in-vention,such as will enableothers skilled in theart to which it appertains to make and use thesame.

The invention has relation to whiffletrees; and the object is to providea simple, durable,

and' inexpensive joint for connecting the whiffletree to the doubletree,so that the parts will not become worn and rattle, as is the case Wherea simple bolt and nut are used for the purpose.

With this object in view the invention con-.

sists in certain features of construction and combination of parts,which will be hereinaf- 'ter described and claimed.

In the accompanying drawings, Figure 1 is a plan view of a vehicle-axle,its pole, the doubletree pivoted thereto,-and its whiffletrees pivotedto the doubletree. Fig. 2 is a fragmentary sectional viewof thedoubletree and the Whiffletree connected together. 3 is a transversesectional view.

In the drawings, 1 denotes the pole of a vehicle, suitable manner, and 3the whiffietrees connected to the doubletree near its ends.

. My invention resides in the connection of the Whiffletree withthedoubletree, and I shall now proceed to describe the same.

To the upper each end is secured a plate A, having an upwardly-projecting annular flange a and a central stud a, which projectsupwardly slightly above the upper edge of the annular flange.

Secured to the under face of each of the whiffletrees intermediate itsends is a plate B, provided with an annular flange b, adapted to [itwithin the flange a of the plate A, with a central boss 19', into whichprojects the stud a of the plate A. Secured to the upper side of thewhiflietree in alinement with the boss b of the plate B is a plate 0,having a central recess or aperture 0.

D denotes a clip having a central stud d, which fits into the apertureof the plate 0, and provided with the bulged portions d, which willpermit of a limited movement of AlthoughI have a means for connectingthe whiffletree to the this joint for the purpose 2 the doubletreepivoted thereto in any" iflailge face of the doubletree near seat, and aclip the Whiffletree, and thereby dispense with the straps usuallyemployed for limiting this,

movement. 1 The lower ends of the clip are closer together and firmlyembrace the don bletree and receive the clip-plate E, which is held inplace by the nuts F. This clip-plate is provided with a loop e, to whichis attached a check-strap G, connected to the axle of the vehicle. Thischeck-strap serves to limit the movement of the doubletree.

For convenience of reference I will term the plate secured to thedoubletree the female member of the coupling and that secured to thewhiflietree the male member of the coupling.

described my invention as 'doubletree, I would have it distinctlyunderstood'that I contemplate and intend to use p of connecting thewhiffletree to the cross-piece of the ordinary thill.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent'of the United States, is

"The combination with the imperforate pieces 2 and 3, of a coupling orjoint consisting of the members A and B secured to the adjacent faces ofthe pieces 2 and 3, the member A comprising an imperforate plate formedwith an upwardly-extending annular flange aand a solid vertical stud a,the member B provided withan annular groove to form two concentricannular flanges located within the b, said member B provided with acentral aperture to receive the solid stud a, a

pate G secured by screws to the upper face and provided with a central Dfor securing the two members together, the limbs, of said clip beingbulged as at d, and the bight provided with a downwardly-projecting studto engage said seat, a clip-plate, and clamping-nuts, all arranged andoperative in substantially the manner herein set forth.

In testimony whereof my hand in presence of two 'subscrib n'esses.

of the piece 3,

I have hereunto set 'ng'wit- FRANK w. cnrcirnnme.
